Dynamic behavior of exposed geomembrane systems in pressure waterways
Giovanni De Cesare, Samuel Luke Vorlet, Roberto Proença Seixas
Geomembrane systems have been used in dams and reservoirs as rehabilitation technology since several decades and are now used worldwide. They act as impervious layer to prevent and mitigate water leakage and damage to structures. They meet the needs of man ...
CRC Press/Balkema2023Dynamics of entrapped microbubbles with multiple openings
Mahmut Selman Sakar, Murat Kaynak, Amit Yedidia Dolev
Microbubbles excited by acoustic fields inside water oscillate, and generate acoustic radiation forces and drag-induced acoustic streaming. These forces can be harnessed in various biomedical applications such as targeted drug delivery and on-chip biomanip ...
2022A Vibrational Technique for in vitro Intraoperative Prosthesis Fixation Monitoring
Kamiar Aminian, Hooman Dejnabadi, Seyed Abdolmajid Yousefsani
Objective: In this paper, a new vibrational modal analysis technique was developed for intraoperative cementless prosthesis fixation evaluation upon hammering. Methods: An artificial bone (Sawbones)-prosthesis system was excited by sweeping of a sine signa ...
2020Vibration Mode of MEMS Ultrasonic Sensors on Buckled Diaphragms with Piezoelectric Resonance Frequency Modification
Vibration mode and resonance frequency of piezoelectric MEMS ultrasonic sensors was investigated on buckled diaphragm structures. The buckling of the diaphragms was introduced intrinsically through residual stress control of the piezoelectric film, and ext ...
IEEE2019Vibration tests on interconnected timber elements using wood-wood connections
Yves Weinand, Julien Gamerro, Jean-François Bocquet
Vibration tests were performed on 3 large-scale timber slabs using wood-wood connections with a span of 8.1 meters. 10 impulsive vibration tests per specimen were performed to estimate the initial natural frequency. Vibrations were triggered using a hammer ...
2019Approximate Cloaking via Transformation Optics for Electromagnetic Waves
Cloaking via transformation optics was introduced by Pendry, Schurig, and Smith for the
Maxwell system and Leonhardt in the geometric optics setting. They used a singular change
of variables which blows up a point into a cloaked region. The same transforma ...
EPFL2018Dynamic pressure probe response tests for robust measurements in periodic flows close to probe resonating frequency
Jürg Alexander Schiffmann, Fatma Ceyhun Sahin
A single-hole probe was designed to measure steady and periodic flows with high fluctuation amplitudes and with minimal flow intrusion. Because of its high aspect ratio, estimations showed that the probe resonates at a frequency two orders of magnitude low ...
Institute of Physics2018Bridge natural frequency estimation by extracting the common vibration component from the responses of two vehicles
Bridge natural frequencies are among fundamental properties of bridges. However, natural frequencies of most bridges remain unknown. Natural frequency identification through acceleration measurement with sensors installed on bridges is not practical if a l ...
Elsevier2017Mathematical analysis of plasmonic nanoparticles: the scalar case
Localized surface plasmons are charge density oscillations confined to metallic nanoparticles. Excitation of localized surface plasmons by an electromagnetic field at an incident wavelength where resonance occurs results in a strong light scattering and an ...
2017Resonance in swirling wakes and sloshing waves
Similarly to mechanical structures, stable flows can exhibit resonance when perturbed by an impulsive or harmonic forcing. Swirling wakes and sloshing waves belong to this kind of flows and manifest large energy response when excited close to their natural ...
